w the bag, but the movement is more or less along a definite path and the person using the bag soon becomes accustomed to the actions of the bag.

It is therefore an object of this invention to provide a mounting for a punching bag which will make the movementsof the bag more or less indefinite, and as a result train the eye of a user more satisfactorily than with the usual type of ba mountin i It is a rther ob ect of the invention to provide a mounting which may be used with standard punchingbags without material alteration of the bag.

These and other objects are attained by the novel construction, combination and arrangement of parts, hereinafter described and shown in the accompanying drawing, consti- 4 tuting a material part of this disclosure, and in which Figure 1 is an elevational view showing one method of mounting the ba Figure 2 is a cross-sectiona View taken along the line 2 2 of Figure 1.

other method of mounting the bag.

Referring to the drawings, a vertical support 3 consisting, in this case, of a metal pipe,

is rigidly held to a base 4 by means of braces 5.

At the upper end of this support, a collar 6 is clamped to the pipe by means of a set screw having a. handle 7 The collar is pror one end of a coil spring 14, the other end 0 v Figure 3 is an elevational view showing anthe spring abuttin the small end of a pearshaped punching ag 15. The'bag is supported by a cord 16 wound about a drum 17 ournalled in the pipe 11 and manipulated by a handle 18. I t I6 W itha bag mounted in the vertical position, as above described, it is obvious that "the spring 14 prevents the bag from following a definite path' when struck and causes the action of the bag to be uncertain, so that a person using the bag must be quick of eye and alert just as he would have to he were he engaged 'in a boxing contest with another person; i i

' Mounted. on the pipe 3 at about the height of the shoulders-of an average man is a collar 19 which is adj ustably clamped to the pipe by means of a set-screwhaving a handle 20;' The collar 19 is provided with a lateral hollow extension 21 and lower and upper hooks 7 22 and 23, to which are respectively attached spr1ngs25 and 24, the sprin s being also attached at their opposite en s to a convolution of the coil spring 26. One end of the spring'26 embraces the extension 21 and abuts the collar 19, while the other end of spring 26 abuts the small end of punching bag 27 which is also abutted by a tube 28, surround- I ing a portion of s ring 26.

The bag 27 is eld against the spring 26 and tube 28 by means of a cord 29 wound about a drum 30, the latter being journalled' 3 in the hollow extension 21 and manipulated by a handle 31. s a -This horizontally positioned bag 27 gives results similar to those obtained with the bag 15, that is, trains the eye of the user to quickly observe the uncertain movements of the bag.

Springs 24; and 25 resiliently maintainthe bag in a horizontal position, at the same time adding to the effect of spring 26.

From the above, description, it will be seen that we have provided a 7 hi hly desirable punching bag a par'atus whic is especially adapted for use y persons training for box- 9 ing contests, as the "uncertain movements of the bags simulate the uncertain movements of aboxing opponent. l

The foregoing disclosure is to be regarded. as descriptive and illustrative only and not as 1 0 restrictive or limitative of the invention, of which obviousgnan embodiment may be constructed,inclu gmany modifications without departing from the general scope herein indicated and denoted in the appended claim.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

A mounting for a punching bag, comprising a vertical tubular support, a collar having a lateral hollow extension, means to clamp the collar to the'support, a pair of hooks on the collar, a coil spring surrounding the extension and abutting the collar at one end,

the other end of'the spring abutting the small natures.
